What is an aluminum battery? Why don't battery cars use lightweight aluminum batteries?

Nowadays, aluminum batteries are so popular, why aren't the bulky battery cars replaced with aluminum batteries? Let us explore it!

Compared with lead-acid batteries, lithium batteries have the advantages of high energy density, long life, small size, and light weight. They are expected to replace lead-acid batteries. Years ago, some industry experts predicted that in the automotive field, lithium batteries can replace about 20% of lead-acid batteries in 2015, and can replace about 30% lead-acid batteries in five years.

Experts have said this use of aluminum batteries is good because of this! However, today, lithium batteries actually replace lead-acid batteries by less than 10%, and it will be very difficult to achieve the goals in the next two years.

According to data recently predicted by industry association leaders, the sales volume of lithium electric vehicles is about 3 million this year, and the total sales volume of electric vehicles is about 32 million. We have all seen that the advantages of aluminum batteries are quite high. Why is the usage rate of electric vehicles so low? The main reasons are as follows:

The cost-effectiveness of lithium batteries is not very prominent, and the repair rate is still high. According to many dealers, the lithium battery cells produced by domestic strong lithium battery companies and ordinary small and medium-sized lithium battery companies have low rework rates, and there is a big gap between high and high prices. The price is also very different. In terms of performance, some lithium batteries have been used for less than one year, and the battery capacity has been greatly attenuated and can no longer be used.

Some aluminum batteries, in addition to small size and light weight, do not have much advantage, the use of which has reached more than 2 years the degree of attenuation of the battery cannot meet the requirements of long distance travel. The most important thing is that the long time of repairing seriously restricts the use of consumers. Once the failure of the lithium battery is repaired, the repair time is usually about one week, allowing consumers to wait too much time and lose confidence in using it. To be honest, I am also unwilling to be a consumer, and what if the matter is urgent?

Why is there such a long time for repair? The reason is that the dealer cannot repair or replace the battery inside the lithium battery, need to be transported to the manufacturing enterprise by express delivery, through the professional equipment for battery maintenance, which is also the key to restrict the large-scale replacement of lead-acid batteries for lithium batteries one.

If you want to improve the use of aluminum batteries, this is a good improvement in repairing this piece! Perhaps aluminum batteries have many advantages and performances, but it is often impossible for consumers to wait for consumption. In the competition of other batteries, aluminum batteries may be compared. Consumers buy less, dealers are reluctant to sell aluminum batteries, and manufacturers are more affected, and the number of production will be greatly reduced.

Of course, if you use the aluminum battery to veto because of the repair problem, then it is not very pit. We know that the quality of aluminum batteries is very light. If the battery car is made of aluminum, it is very good and it won't look so heavy but Aluminum batteries also have a big disadvantage, that is, they are more delicate, worn, blown, and easy to break. If used on a battery car, the repair rate is high. For these reasons, the bulky battery car does not use aluminum batteries!

Although the battery of the current battery car does not use aluminum batteries, with the advancement of technology, there will always be one day, and the battery car can also be replaced with an aluminum battery.
